Triggered by new reactivity patterns discovered in 2000,[1] gold catalysis has become a very successful sector of catalysis research.[2] After methodology development and mechanistic studies in the last years applications in total synthesis became a hot topic in gold catalysis. Typical intermediates would be vinylgold/arylgold species or gold carbene species, recently also gold vinylidene intermediates,[3] in the last two years even photoredox catalysis with gold complexes evolved, including catalytic cycles involving gold (I) and gold (III).[4] Gold-catalyzed reactions involving functionalized gold carbene intermediates represent another new and significant variation of the reactivity patterns of gold catalysis. New reactivity patterns will be discussed in detail with a number of new reactions, the presentation will combine both experimental and computational results. Examples will involve the use of anthranils, 1,2,4-oxadiazoles and 1,3,5-triazinanes. Furthermore, oxygen transfer to the functionalized carbene centers and insertions into alkyl-C,H bonds will be addressed in detail.
